The stochastic behavior of FM-clicks in an unmodulated carrier plus noise is studied in terms of the conditional behavior of stationary Gaussian processes after level crossings. By a systematic use of thc Slepian model processes it is shown that the normalized shape of a positive FM-click approaches a certain rational function with simple random coefficients as the carrier-to-noise ratio tends to
Synthetic biology, a branch of the life sciences, can be summarized as the deliberate attempt to design living organisms. It is an emerging technoscience and a potential platform technology portrayed as possibly the next industrial revolution. This thesis is an inquiry into synthetic biology; an exploration based on observations in text. An explorative tool is the question: What is synthetic biolo
Introduction: This paper reports results from an ethnographic study of teacher trainees’ information activities in digital, group-based learning and their relation to the interplay between use and appropriation of digital tools and the learning environment. Method. The participants in the present study are 249 pre-school teacher trainees in Sweden. Three key informants and their teams were followe
Parallel evolution occurs when a similar trait emerges in independent evolutionary lineages. Although changes in protein coding and gene transcription have been investigated as underlying mechanisms for parallel evolution, parallel changes in chromatin structure have never been reported. Here, Saccharomyces cerevisiae and a distantly related yeast species, Dekkera bruxellensis, are investigated be
The houses from the million homes program are in severe need of renovation. A problem that arises when housing companies renovate are extreme rent increases. In many instances it exceeds the tenants’ payment ability. Resulting in a renoviction process where the tenant has no choice but to move. This study aims to examine how the housing company Fastigheter AB Trianon has worked with these necessar
Next-generation sequencing experiments have shown that microRNAs (miRNAs) are expressed in many different isoforms (isomiRs), whose biological relevance is often unclear. We found that mature miR-21, the most widely researched miRNA because of its importance in human disease, is produced in two prevalent isomiR forms that differ by 1 nt at their 3' end, and moreover that the 3' end of miR-21 is po
This thesis deals with the task of modeling a web server and designing a mechanism that can prevent the web server from being overloaded. Four papers are presented. The first paper gives an M/G/1/K processor sharing model of a single web server. The model is validated against measurements ands imulations on the commonly usedw eb server Apache. A description is given on how to calculate the necessar
Increased blood glucose after a meal is countered by the subsequent increased release of the hypoglycemic hormone insulin from the pancreatic beta cells. The cascade of molecular events encompassing the initial sensing and transport of glucose into the beta cell, culminating with the exocytosis of the insulin large dense core granules (LDCVs) is termed "stimulus-secretion coupling." Impairment in
We study the associated production of a charged Higgs and a W boson in high-energy pp collisions at the LHC. This is an interesting process for charged Higgs discovery, or exclusion, since the production cross section could depend strongly on the model, offering potential discriminating power between supersymmetric extensions of the standard model with minimal or extended Higgs sectors. We compute
Since a tightly regulated complement system is needed for a successful pregnancy, we hypothesized that alterations in complement inhibitors may be associated with idiopathic, recurrent miscarriage. We sequenced all exons coding for three complement inhibitors: C4b-binding protein (C4BP), CD46 and CD55 in 384 childless women with at least two miscarriages that could not be explained by known risk f
The aim of the present study was to enhance our understanding of vegetables as living organisms, interacting dynamically with the environment, and to explore the possible influence of metabolic changes on subsequent processing operations. Growing conditions, harvesting and handling in the packing house and storage conditions are key events leading to a defined “physiological status” of the vegetab
In the early 1990s, Indonesia was seen as one of the post war success stories. The country was boasting an impressive growth record and had seen the number of poor continuously decline. This picture of Indonesia stood in stark contrast to the situation only 30 years earlier when the economy was in a shambles and starvation was a real threat. At the core of this change in Indonesia lies the transfo
Attosecond pulses in the extreme ultraviolet (XUV) spectral range are today routinely generated via high-order harmonic generation (HHG), when intense ultrashort laser pulses are focused into a gaseous generation medium. The effect is most easily understood in a semi-classical picture [1]. An electron can tunnel ionize from the distorted atomic potential, pick up kinetic energy in the laser field,
My paper studies the nominal system in a dialect of Småland, spoken in Urshult,as it has been coded and transcribed in a volume by Swea Johansson, a native speaker of this dialect. In this variety, a large portion of the weak feminines, in modern Swedish roughly nouns ending -a, for example penna ’pencil’, instead end in -e, penne ’pencil’. Furthermore, the definite form frequently ends in -na, pe: My paper studies the nominal system in a dialect of Småland, spoken in Urshult,as it has been coded and transcribed in a volume by Swea Johansson, a native speaker of this dialect.

In a world of nearly 10 billion people, competition for the conditions of life and wealth can only accelerate. Our contention is that with such increasing competition, more and more material as well as immaterial things will be turned into resources – a process that we suggest to label resourcification.Resourcification is not another term for processes of economisation such as commodification and
The extraction of spectral information in the inversion process of time-domain (TD) induced polarization (IP) data is changing the use of the TDIP method. Data interpretation is evolving from a qualitative description of the subsurface, able only to discriminate the presence of contrasts in chargeability parameters, towards a quantitative analysis of the investigated media, which allows for detail
Companies are constantly being pressured to innovate in order to stay competitive in the short run and have new offerings in the long run. One way of boosting innovation is to develop idea support systems that go beyond the traditional methods and tools. Through a qualitative study, this paper explores the lessons learned from developing an online platform for idea generation, and discusses it in
Due to increasing oil price and environmental concerns, current European initiatives are aiming to increase the share of Biofuel used for transportation from approx. 2 % (2005) to 5.75% in 2010. The production capacity of bioethanol in Germany alone has therefore to increase during this period from 0.7 mio. m³ to 1.8 mio. m³ 1. The feed stocks of current bioethanol concepts are sugar and starch
This paper uses the three spatial design workshops D-Thinking Urban Strategy; Re-Ts >> Space(s) Innovation, and ZHUuGROUND 14 as the intellectual framework to evaluate experimentation as a pedagogical model in current interdisciplinary design education. The three workshops were conducted by the independent teaching and research organization, the Research Institute for Experimental Architecture (RI
